PSU upgrade for GTS450

[darkly scanner]

I'm upgrading my GPU from a 9800GT to a GTS450 (GDDR5 ver) which I managed to get off a friend cheaply but the problem is now I believe my current PSU is incompatible due to the Amps on the 12v are just too low (requirements is 22Amps).

This (generic) 500 WATT ATX POWER SUPPLY. Will this work? I cannot really afford my computer to go bang just yet.

Additional PC spec;
CPU: i5-760 (with intel generic heatsink)
MB: ASUS P7P55D-E LX
HD: WD10EARS
disc drive:SH-S223L

If you could offer another better suggestion, my max price range is £35 and ideally at least 450w.

Hi. Do not go with that PSU unless you want to risk your PC to go bang. Go with the XFX ProSeries Core Edition 450W for a couple of £ more.

If you really must buy from Amazon, then get the CX430.

The problem with that PSU is that it's not really a 450W PSU. It's MAX power output is 450W but i would be surprised if it's continuous output was even 350W if that. For that card (or any card that requires external power) I would suggest a power supply with AT LEAST 500 Watts of continuous power and preferably a single rail design with at least 38 amps on the rail. Afew suggestions would be
